Thanks Jgimmi ! I installed sleuthkit .. but fls can't find the deleted file .. is ceating an image of the home partition mandatory ?? then I'd rather redownload those iso files .. lol ..
yet .. learning is better than just retreaving those files :-)

Your questions about The Sleuth Kit are likely to be answered by spending time with the documentation and resources at www.sleuthkit.org -- start there. This forum is not the proper medium for getting instruction on the basics of digital forensics.
